### Aura-2 Speed and Pronunciation Controls require an updated voice-pack

The new **Aura-2 Speed and Pronunciation Control** features in this release are powered by an updated Aura-2 English voice-pack model. If your deployment is using an Aura-2 English voice-pack from before the April 2026 release (e.g., the `2025-04-15.0` version of the voice-pack), requests including the `speed` or `pronounce` parameters will return `400 Bad Request`.

To enable these features, contact your Deepgram representative to obtain the latest Aura-2 English voice-pack (`2025-04-15.4` or later) and replace the existing voice-pack file in your models directory. The official Deepgram Helm chart and sample values files in `deepgram/self-hosted-resources` (chart `0.34.0` and later) already point to the correct UUID; you only need to use the latest Deepgram configuration files and update the model file on disk.
